Rose plant named `Twomin`

ABSTRACT

A new miniature market class rose plant producing orange red flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the miniature rose class, which was originated by my crossingas seed parent and pollen parents two unnamed and unpatented seedlingsof my creation which, although have hybrid tea in their heritage,conform best to the miniature market class. The varietal denomination ofthis new rose is "Twomin".

Among the novel characteristics possessed by this new variety whichprimarily distinguishes it from its parents and all other varieties ofwhich I am aware are its unusual orange red flowers which open well uponaging. The new variety is especially suited for growing in outdoorgardens and exhibits improved vigor and flower production. The plantblooms freely under natural conditions.

Asexual reproduction by propagation by budding and rooting cuttings ofthe new variety, as performed in Pleasanton, Calif. and Watsonville,Calif., shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows a typical specimen of the flower andvegetative growth of the new variety depicted in color as nearly true asit is reasonably possible to make the same in a color illustration ofthis character.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.). The terminology used in color descriptions hereinrefer to plate numbers in the aforementioned color chart.
